A night of horror in northwest Houston came after a mass murder inside one home. The bodies of six children and two adults were found inside the residence.
The night started as a welfare check but when Harris County deputies arrived, no one answered.
They soon found out 49-year-old David Conley was in the home -- and he had a warrant for aggravated assault on a family member.
"Deputies had surrounded the house and were checking through the windows," said Deputy Thomas Gilliland of the Harris County Sheriff's Office.
"At that point the body of a young juvenile was seen through a window," he says.
That's when officers decided to enter the home.
When they entered, they say Conley began shooting inside the house and deputies stepped back out. A hostage negotiator was finally able to get Conley to come out --- and just like that he appeared -- seemingly calm and compliant.
In the light of day, shocked neighbors try to piece together the tragic story.
"We were in shock," says Yessica Razo, the front door neighbor of the victims.
"We would always see policeman outside their doors."
While the story continues to unfold, Conley is charged with capital murder.
